Seitz and Stackelberg on Oligopoly.
No full textThis essay deals with the contribution of Seitz and Stackelberg on oligopoly. Stackelberg's theory on price leadership has been taken up by Seitz in his dissertation of 1965. The author summarizes the debate in Germany in the beginning of the sixties on oligopoly theory between Krelle, Ott, Heertje, Helmstadter und Seitz. He looks back from a game theoretical point of view.oligopoly, Nash-equilibrium, Stackelberg, Seitz, Krelle, game theory, Cournot, two-period game, one-shot game

No full textMultiple Causal Links between Magnocellular-Dorsal Pathway Deficit and Developmental Dyslexia
No full textAlthough impaired auditory-phonological processing is the most popular explanation of developmental dyslexia (DD), the literature shows that the combination of several causes rather than a single factor contributes to DD. Functioning of the visual magnocellular-dorsal (MD) pathway, which plays a key role in motion perception, is a much debated, but heavily suspected factor contributing to DD. Here, we employ a comprehensive approach that incorporates all the accepted methods required to test the relationship between the MD pathway dysfunction and DD. The results of 4 experiments show that (1) Motion perception is impaired in children with dyslexia in comparison both with age-match and with reading-level controls; (2) pre-reading visual motion perception-independently from auditory-phonological skill-predicts future reading development, and (3) targeted MD trainings-not involving any auditory-phonological stimulation-leads to improved reading skill in children and adults with DD. Our findings demonstrate, for the first time, a causal relationship between MD deficits and DD, virtually closing a 30-year long debate. Since MD dysfunction can be diagnosed much earlier than reading and language disorders, our findings pave the way for low resource-intensive, early prevention programs that could drastically reduce the incidence of DD
Spectrum of Large and Medium Vessel Vasculitis in Adults: Primary Vasculitides, Arthritides, Connective Tissue, and Fibroinflammatory Diseases.
No full textPURPOSE OF REVIEW
To provide a comprehensive overview of the spectrum of large and medium vessel vasculitis in adults with primary vasculitides, arthritides, connective tissue, and fibroinflammatory diseases as well as vasculitis mimics, for an efficient differential diagnosis and initial diagnostic approach.
RECENT FINDINGS
Imaging has had a tremendous impact on the diagnosis of medium to large vessel vasculitis, now often replacing histopathologic confirmation and identifying new disease manifestations (e.g., intracranial disease in giant cell arteritis; vascular manifestations of IgG4-related disease). Novel diseases or syndromes involving blood vessels have been described (e.g., VEXAS-Syndrome with polychondritis). The use of the terms "medium" or "large" vessel varies considerably between medical specialties. The differential diagnosis of large and medium vessel vasculitis is becoming increasingly complex as new entities or disease manifestations of known inflammatory rheumatic diseases are regularly identified. A more precise and widely recognized definition of the vessel sizes would make future research more comparable
Spectrum of Large- and Medium-Vessel Vasculitis in Adults: Neoplastic, Infectious, Drug-Induced, Autoinflammatory, and Primary Immunodeficiency Diseases
No full textPURPOSE OF REVIEW: To provide a comprehensive review of drugs and neoplastic, infectious, autoinflammatory, and immunodeficiency diseases causing medium- to large-vessel vasculitis in adults with emphasis on information essential for the initial diagnostic process. RECENT FINDINGS: Entities with medium- to large-vessel vasculitis as clinical manifestations have been described recently (e.g., adenosine deaminase-2 deficiency, VEXAS-Syndrome), and vasculitis in established autoinflammatory or immunodeficiency diseases is increasingly being identified. SUMMARY: In the diagnostic process of medium- to large-vessel vasculitis in adults, a large variety of rare diseases should be included in the differential diagnosis, especially if diagnosis is made without histologic confirmation and in younger patients. Although these disorders should be considered, they will undoubtedly remain rare in daily practice.

No full textFrédéric Seitz. The century-long neglect of metal in French construction : a question of cost ?
The high price of metal is often invoked reasons to explain its minimal use in French architecture and building. The author uses informations taken from Price Series to evaluate this argument for the period 1875 to World War 2. He argues that the underuse of metal cannot be explained by economic considerations. Instead he focuses on the actors involved in metallic construction : producers, masterbuilders and contractors.Frédéric Seitz. Le métal mal-aimé de la construction en France depuis un siècle : des raisons de coût ?
Le coût du métal et de sa mise en œuvre est l'une des raisons souvent invoquée pour expliquer la faible part qui est réservée à ce matériau dans l'architecture et la construction françaises. L'auteur
examine ici cette question pour la période qui s'étend de 1875 à la veille de la seconde guerre mondiale, à partir des informations contenues dans les Séries de Prix. Concluant que le sous-emploi du métal dans le cadre bâti ne peut s'expliquer par des considérations économiques, il suggère que cette problématique soit abordée par référence non pas seulement au matériau lui-même, mais aussi au rôle des acteurs de la construction métallique : fabriquants de matériaux, maîtres d'ouvrage, maîtres d'œuvre et entrepreneurs.Seitz Frédéric.

The great island : some observations in and about Newfoundland
No full textSeitz's interest in Newfoundland developed after having been befriended by a Newfoundland dog as a young boy. In December of 1926, the author set out on a journey to visit the ancestral home of his old friend, this book being the outcome of his travels. Seitz paints a very vivid picture of Newfoundland for his readers, skillfully describing Newfoundland and Labrador, the people, and their way of life while also relaying the facts about the colony's mineral resources, fishing industries, religion, and politics. The author also includes details which would be of particular interest to tourists, such as a brief history of the colony, hunting and fishing opportunities and regulations, the Newfoundland dog, and modes of transportation available to get to Newfoundland and for use when one has arrived
